While we are waiting for a full announcement, you should be prepared for the upcoming change.
While Bunge is scheduling the final event for the first Destiny, some additional information about the upcoming sequel was revealed. If you wished for a full character transfer, that won’t be the case, unfortunately.
Sequels represent the start of a new adventure for every player, with new worlds to explore, new stories to tell, new powers to acquire, new loot to earn, and much more. This led us to a decision that would enable us to serve both the game and the player’s best interests: Destiny 1 power, possessions, and Eververse-related items and currency will not carry forward. They will, however, remain accessible to you in Destiny 1.
The good news is that your character customization will be transferred to Destiny 2. It was stated that “the class, race, gender, face, hair, and marking selections for all characters that have achieved Level 20 and completed the Black Garden story mission will carry forward.” It’s also revealed that some forms of rewards will be waiting for Destiny’s veterans.
